Patient: Male, 76-year-old
Final Diagnosis: Extensively drug-resistant
Enterococcus faecalis
diabetic-foot myositis and osteomyelitis
Symptoms: Fever, pain to his left lower foot and altered level of consciousness
Clinical Procedure: Surgical debridement combined with the administration of teicoplanin plus rifampicin in the outpatient setting, completing in-total a twelve-week course of antibiotic therapy
Specialty: Endocrinology and Metabolic • Infectious Diseases • General and Internal Medicine
Objective:
Rare disease
Background:
Foot ulcers are high-morbidity and debilitating complications of diabetes mellitus, and carry significantly increased rates of associated major amputations. They contribute to significantly worse quality of life. Osteomyelitis is a frequent complication of diabetic foot ulcers, since bacteria can contiguously spread from soft tissues to the bone, involving the cortex first and then the bone marrow. Unfortunately, clinically unsuspected osteomyelitis is frequent in persisting diabetic foot ulcers. It is associated with limb amputations and increased mortality.
Case Report:
We describe a 76-year-old man with long-standing insulin-treated type 2 diabetes, who experienced extensively drug-resistant
Enterococcus faecalis
diabetic foot myositis and osteomyelitis associated with sepsis. He was successfully treated with surgical debridement combined with the administration of teicoplanin plus rifampicin in the outpatient setting, completing, in total, a twelve-week course of antibiotic therapy.
Conclusions:
Clinically unsuspected osteomyelitis in patients with persisting diabetic foot ulcers has been associated with infections from highly resistant bacteria. Early and accurate diagnosis of diabetic foot osteomyelitis, as well as proper therapeutic approach (antimicrobial and surgical), is of great importance to reduce the risk of minor and major amputations, septic shock leading to multiple organ failure, and overall mortality.
